According to national regulations, all the processes of every criminal case will be recorded in video and stored permanently, and criminal cases in the entire district, city, and province will occur one after another, and the videos will also be stored one by one. The elapsed time and the accumulation of cases , The storage cost of video will be a big problem.
The Aerospace Security Network received a request for criminal investigation video storage from the Xinjiang Public Security Bureau. Immediately launch the corresponding lossless high-definition video and meet the H.264, H.265 compression storage solution of video storage.
Project background:
In criminal investigation cases, video, as an extremely effective aid in solving crimes, greatly increases the probability of successful case detection and conviction. It is an important means to cooperate with the public security and judicial departments in fighting crimes and maintaining social stability. However, incidents of video leaks frequently occur, and man-made theft and dissemination have extremely adverse effects on police work.
Project requirements:
Real-time watermark rendering of video sources in the video network to prevent video theft and recording. Once the video is leaked to the Internet, the traceability system can be used to quickly check the source of the video image leak.
Solution design: You
can log in on any terminal computer through a third-party platform client, and the watermark server will comprehensively record the MAC, IP address and user of the login terminal The time information of login and access generates a video watermark, which is embedded in the obtained video stream image in real time in the form of a QR code, etc., to achieve low-latency, high-stability and reliable video stream processing and transmission, and to meet a certain scale of concurrent access calls Video requirements. 
Customer value:
Solve the problem that the source of cloud video data cannot be traced, effectively find the source of leaked video, control adverse effects in time, and provide favorable technical support for information sealing and control.
Aerospace Safety Net's VDMS video data management system launched BBW video coding technology, which aims to provide advanced solutions for efficient compression of high-definition video data. Compared with H.264, the video compression standard can be increased by about 10 times.
